You have a 30g quarter on an old LP turntable at a radius of 30 cm from the turntable's center. If the coefficient of Friction between the coin and the turntable is 0.6, at what speed will the coin slide off the turntable? Hint: this is a circular motion problem. To find the necessary speed use the circumference of the circle the coin travels on.
Need Step by Step Solution.

    When it starts the slide, the force of friction is just equal to centripetal force.

    mass*angular speed *radius= mu*mass*g

    solve for angular speed.

    How would I convert that to m/s
